Application filed November 6, 3.913. Serial No. 799,6:93-

To all wimmt't may concern Be it known that we, JAMES Hman Comes and Ronnn'r BnAeKENnIDon Pennine citizens of the United States, the county of Jackson and State of kla lio-nia, have invented certain net/v. and useful improvements in -Revolving Egg-Supports for incubatore; and We do declare the "fob lening to be a full. clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to incubatore and more particularly to egg turners therefor and the primary object of .the invention is to pro\.'ide a simple and eilicient device of this character which will enable a large number oi? to be turned at one and the saine tinie vwithout danger of breaking the same. rlhis object is carried out by constructing the een tray and turner in the manner hereinafter more fully described and claimed, and as shown in the drawings Wherein- Figure l, Sheet l, is an vend elevation of a deep tray or drawer containing a pair of our revolving turners. l* 2 lis a cross section through the saine showing the outer half oi? the uppermost cylinder removed. Figi. is an enlarged cross section through one of the cylinders, showing the construeiion of its screen wire and strips. Fig. is a vertical section on the line 4-4 of Fig. 2.

r `lie egg; turner forming the principal fea-- ture or' the present invention comprises a rather deep tray (hereinafter called a drawer) l having' notches Q in its ends for removably receiving tlieshatts 3 and i ot a plurality of drums7 each druin in turn carrying a niuuber of cylinders into whiifli the eine are placed. llach of said shafts at the frm/it end ci the dra u'cr is squared as liown, and when a kry is applied the eniire drum ran la rotated for a partial revolution with cui' removing it 'rou'x the dra\.ver or rei'uovino; the drawer from place: in tart. the v aired eidi'eiuiiy might project entirely through the front door il ille incubator casiuff. :rid the key could he applied thereto without opening said door. ille have showu trio oi said drums iuouuted .side by side in each drawer` but obviously this is uol nei-essury as there could he a greater or lesser number. llaf-h drum is made up of wooden corr blocks 5, to the luier faces of which are secured metal heads (l et' polygonal, conteur residing at Altus, inA

(herein shown as having tive straight sides), and the shafts project through said blocks and heads and serve as supports as above described. These heads Carry between them 16 mesh screen wire, the inner parts or halves et the cylinders being closed .at their extremities by the heads and attached thereto, and the out-er parts 8 being removable. Alone each edge of the inner part is secured a lll-siliaped guide strip 9, and each edge of the outer part Sis bent out-Ward and laid over a metal tongue 10, which lat-ter in turn in then folded over onto the edge and the parts soldered together. The tongues thereafter may slip into the slots of the guide strips 9, so that the outer part 8 is rendered removable from the inner part 7. Each end of the outer part is closed as at il in an suitable manner, but preferably by Wire mesh as indicated. This leaves the outer part or halt oi the cylinder removably attached to the inner part or halt', and the latter carried by and forming part of the drum which is rotatably mounted in the drawer. When novi' the outer half oi any cylinder is Withdrawn, the inner halt may be filled with eggs as indicated and the outer haiiz slipped back into place, then the drum is rotated for a partial revolution to bring the outer halrn of the next cylinder into position to be moved longitudb nally on the inner hall", across the end of the drawer, and this cylinder in turn is filled with eggs. Finally atter all cylinders are filled, they balance the drunl on its trunniens or pivots, and the revolving egg support may be turned step by step at any time when it is desired to turn the eggs.

lVe have 'found by experience that this device eliminates the possibilty of breaking7 the eggs in handling; or turning them, and effects considerable saving;V iu the amount of lluel coi'isunied in proportion to the number i el eggs.

These egg tui-ners will hold about twice as niauy egggrs as itis possible to place on ay floor space equal to the diameter ot' the cylinders, because obviously several of the cylinders in any druiu are supported above the floor space.

lu setting an incubator )rovided 'with this arg1 turner, two ot' the drums are supl plied with eggs three days prior to fillingl the other two, and alter the eggs have .re

and around the core formed by the blocks a number of tvvopart cylinders 7 of number lll) inained in the cylinders eighteen days the vare taken out. and placed in other and pre"- erably shallower trays elsewherev in the incubator and the hatch finished there, the cylinders just emptied being refilled so that continuous incubation may be kept up. fn said shallower `trays the chicks have ample opportuni ty to escape from the yeggs when they break the shell..

In the use of the eggturners above described and shown in the drawing any preferred forni of heating and ventilating apparatus may be used, and as the same forms no part of this .invention a showing and description thereof are entirely omitted from the drawing and specification respectively.

From the foregoing, i, will be seen that we have provided a simple, inexpensive and efficient means .for carrying ont the objects of the invention and while we have particularly described the elements best adaptled to perform the functions set forth, it is obvious that .various changes in form, proportion and in the minor details of construction may be resorted to without departing from the spirit 'or sacrificingA any of the,

principles ofthe invention.` hat is claimed as n'ew is:

l. The herein described egg turner coinprising adruin made up of a core, polygonal heads at the ends of said core, and shafts projecting from the ends of the core through the heads;- and a series of two-part foralninous cylinders carried by said core.

2. The herein .described egg turner coinprising a drum made up of a core, polygonal heads at the ends of said core, and shafts projecting from the ends of the core through the eads, one end. of said shafts being squared; a' series of two-part foraininous cylinders carried by said core; and a drawer having notches in the upper edges of its ends 'for receiving sai-d shafts therein.

The herein described egg turner coxnprising drum made up of a core.,`polygonal heads at the ends of said core, and shafts projecting from the ends of the core through the heads; and a series of two-part foraini` nous cylinders carried by said core, the inner part of each cylinder being disposed between the heads and having grooved guides along its edges, and the outer part ha\ ing' its ends closed and tongues along its edges slidably mounted within said guides.l

4. The herein described egg turner cornprising a drum made up of a core, polygonal heads at the ends of said core, and shafts projecting from the ends of the core through the heads; and a series of two-part foraminous cylinders carried-by said core, the inner part being disposed between said heads and having its edges turned outward, U-shaped guide strips secured to said edges and standing beyond` the edges of the heads, the i outer part having its ends closed and its edges bent outward, and sheet-1netal tongues soldered to said outturned ably mounted .within said for the purpose set forth.

5. In arevolving egg support for incu- 'bators, the combination with a, core, heads carried by' :the extremities thereof, and means for supporting the eolie for rotation on its axis',- of a seriesof foraminous cylinders whose inner-halves are secured between said heads and whose outerA halves are Inovably connected with their inner halves.

'6. In a revolving egg support for incubators, the combination with a core, heads carried by the extremities thereof, and

i means for supporting the core for rotation on its axis ;A of. a series of foralninous cylinders whose inner halves are secured between said heads andhave grooved guides along their edges, and Whose outer halves are slidgrooved guides,

. -ably mounted over the inner halves' and have radially projecting tongues along their edges engaging said guides.

7. In an egg support for incubators, a rotatable drum, supporting means therefor, and a series o two-part cylinders carried thereby, the inner sections of said cylinders being disposed substantially Within the druni and the outer sections thereof projecting therebeyond.`

In testimony whereof lwe have hereunto set our hands in presence of two subscribing witnesses.
